What was behind Johnny Depp and Amber Heard's divorce? According to TMZ's sources, Depp's family—his two children, his sisters, and his mom, who died just days before Heard filed for divorce—despised Heard and believed she treated Depp poorly. After Depp moved his mom into his and Heard's LA home earlier this year, there was quite a bit of tension, sources say, and Depp's mom spoke openly about her belief that Heard was just using Depp for his money and to increase her own fame. But a source who spoke to People paints Heard as "just a regular super cool hipster chick living with roommates who dated girls," who was actually overwhelmed upon getting engaged to Depp.

"At their engagement party she kind of got cold feet," the source says. "She was just like what is this scene and what am I doing here? She kind of couldn't believe it was her life now." Either way, their romance was rocky: E!, the Daily Beast, and People run down some of the signs they were headed for a split, including the alleged facts that they reportedly fight often and barely communicate when they're off working on their own projects, and that there have been plenty of reports of drama between the couple since they first got together. More recently, Heard was missing from Depp's recent promotional appearances for Alice Through the Looking Glass, and Depp was not at Heard's side for the most recent Met Gala in May or her 30th birthday celebration in April. (The divorce could end up a $400 million battle.)
